4.1 General Installation Notes

4.1.1 Before installing new parts, remove any rust preventative, protection grease etc.

4.1.2 Check before immediate installation for possible transit damage.

4.1.3 Components which have been stored for a long time (over 1 year) should be re-lubricated in working conditions before they are put into operation.

4.1.4 Before putting the Range-N bevel gearbox(es) into service, the User must ensure that the plant in which it is installed complies with all applicable directives, especially those regarding health and safety at work.

4.1.5 Handle the bevel gearbox with care. The Range-N bevel gearboxes should be handled with care to avoid damaging the machined drive shafts.

4.1.6 Before putting the units into service, check the lubricant level. If necessary top up the lubricant to the required level.

4.1.7 All Neeter Drive Range-N gearboxes are shipped without lubrication, except for grease filled units.

4.1.8 Do not mix oil or greases of different nature or specifications.

4.1.9 If the same type of lubricant already in use is not available, remove all of the existing lubricant completely and flush its interior thoroughly with a light solvent before refilling with a new lubricant.

4.1.10 The structure on which the Range-N bevel gearbox(es) are mounted must have ample strength to carry the maximum torque, and should be rigid enough to prevent undue deflection or distortion of the bevel gearbox supporting members.

4.1.11 It is essential that the Range-N bevel gearbox(es) be carefully aligned during installation so that the drive shafts are running true and the connecting shafts are exactly in line with each drive shafts.

4.1.12 When installing several bevel gearbox(es) to move a common item / structure, the gearboxes should first be connected to the structure (refer 4.4). The bevel gearbox drive shafts should then be connected taking care not to turn the drive shaft and lose the any relative position for the installation.

4.1.13 After the Range-N bevel gearbox(es) is installed, shafting, gearboxes, motors, etc., are coupled together it should be possible to turn the main drive by hand (no load on condition). If there are no signs of binding or misalignment, the bevel gearbox system is then ready for normal operation.

4.1.14 After the Range-N bevel gearbox(es) are installed, they should be operated through their full rotation ten to twenty times under minimum load conditions. If the arrangement operates satisfactorily and there are no signs of binding or misalignment the Range-N bevel gearbox(es) are ready for normal operation. Refer to section 5 for typical operating performance checks.

www.powerjacks.com 13 4 Installation

4.2 Unpacking and installation

4.2.1 Remove the Range-N bevel gearbox(es) from their container. Dispose of the packaging material and the desiccant in an environmentally friendly way.

4.2.2 If it is necessary and in order to avoid damages, please use soft straps to transport or mount the bevel gearbox.

4.3 Mounting

4.3.1 Before starting assembly work, check the directions of rotation of all, gearboxes and drive motors with regard to the required direction of rotation of each gearbox in the application.

4.3.2 All components must be carefully aligned, as alignment errors increase stress and power consumption and lead to overheating and premature wear.

4.3.3 When installing bevel gearbox(es), ensure that the mounting face is flat and square to the drive line, to within 0.4/1000 millimetres.

4.3.4 Before attaching the drive unit, the bevel gearbox should be turned through 10 to 20 revolutions by hand, without load. Variations in the amount of torque required and/or marks on any guides indicate alignment errors. Loosen the relevant mounting bolts and adjust positioning until the correct alignment is achieved.

4.3.5 All mounting bolts must be re-tightened after a short period of operation.

4.3.6 Mount the bevel gearbox by fixing the bevel gearbox body to the structure by either its standard base mounting points or via a mounting accessory like a base feet. The drive shaft ends should then be coupled to the associated drive line(s).

4.3.7 Take care when fitting couplings. A blow on a shaft end could cause gear set damage.

4.3.8 Shaft alignment is critical, check on installation

4.4 Drive Motor

4.4.1 Power Jacks recommend that when you purchase a bevel gearbox requiring a motor mounted directly to the bevel gearbox this is purchased as a complete item from Power Jacks. The motor is then pre-assembled to the bevel gearbox. If you have opted to fit a motor yourself below is a typical procedure for common motor types.

4.4.2 Before mounting the drive motor, check the direction of rotation of the bevel gearbox drive shafts relative to the motion of the drive system. Also check the operation of any limit switches fitted to the unit.

4.4.3 Place the motor into the mounting position next to the bevel gearbox.

4.4.4 Connect the motor to the power source and switch on the motor. Check the direction of rotation, in association with the safety limit switches (if necessary, change the direction of the motor shaft rotation). Once this check is complete disconnect the motor from the power source.

4.4.3 For standard designs the motor directly plugs into a hollow input shaft on the bevel gearbox. However for some special designs a flexible with elastomeric element is used to connect the two drive shafts.

4.4.4 If this is the case attach one hub of the coupling half to the drive shaft of the bevel gearbox.

4.4.5 Push the elastomeric element (spider insert) onto the coupling hub now on the gearbox.

4.4.6 Mount the second coupling hub onto the drive shaft of the motor.

4.4.7 Attach the motor to the motor adapter flange using 4 screws. Remember to radially orientate the motor to the correct position for your application.

4.4.8 Gearboxes with integrated motor mounting flanges share common components with the standard gearboxes, however the motor flange and input are different and vary on every unit dependant upon ratio and flange size / style. For a parts list of items in a motor-flanged unit please contact Power Jacks with the unit model number and serial number.

4.5 Limit Switches – Fitted To Protective Shaft Cover

4.5.1 Power Jacks recommend that when you purchase a bevel gearbox requiring limit switches mounted directly to the bevel gearbox this is purchased as a complete item from Power Jacks. The limit switches are then pre-assembled to the bevel gearbox provided suitable to transport. However always reset and check limit switch operation when installing the bevel gearbox. The following procedure is for limit switches fitted to a protective cover for a drive shaft (e.g. backup manual drive).

4.5.2 Detach the protective shaft cover by loosening the mounting bolt.

4.5.3 Fit the limit switch to the cover.

4.5.4 Fit the cover with limit switch to the gearbox and bolt in position.

4.5.5 Check that the limit switch triggers at the correct point when the cover is unbolted from the gearbox.

4.5.6 If necessary, repeat the procedure.

4.6 Limit Switches – Rotary Cam Type (RLS)

4.6.1 Power Jacks recommend that when you purchase a bevel gearbox requiring a Rotary cam type Limit Switch (RLS) mounted directly to the bevel gearbox this is purchased as a complete item from Power Jacks. The RLS unit is then pre-assembled to the bevel gearbox. If you have opted to fit a RLS unit yourself below is a typical procedure for common RLS unit types. However always reset and check limit switch operation when installing the bevel gearbox.

4.6.2 Before mounting the RLS unit, check the direction of rotation of the bevel gearbox drive shafts relative to the motion of the drive system.

4.6.3 Place the RLS unit into the mounting position next to the bevel gearbox.

4.6.4 Typically a flexible beam coupling is used to connect the two drive shafts.

4.6.5 Attach the beam coupling to the drive shaft of the bevel gearbox.

4.6.6 Attach the RLS unit to the adapter flange using 4 screws. Make sure that the drive shaft of the RLS unit fully engages in the beam coupling. Tighten the clamp screw of the beam coupling. Remember to radially orientate the RLS unit to the correct position for your application.

4.7 Regulations

The following regulations must be complied with: • The relevant local regulations for the prevention of accidents. • Generally recognized safety regulations. • National regulations.

16 www.powerjacks.com Operation 5

5.1 Operational Recommendations

5.1.1 Select a bevel gearbox which has a rated capacity greater than the maximum input power that may be imposed on it.

5.1.2 The maximum input shaft speed for these bevel gearboxes should not exceed 3000 R.P.M. Refer to Power Jacks Limited for higher shaft speeds.

5.1.3 The lead screws should not be permitted to accumulate dust and grit on the threads. If possible, lead screws should be returned to the closed position (retracted) when not in use.

5.1.4 If equipped with bellows boot the boot must not be compressed bellow its minimum height (consult Power Jacks product literature or engineers).

5.2 Operational Features

5.2.1 Does it matter which shaft I use as my input

As standard the units are supplied with the shaft 1 or sometimes referred to as A as the input. It is also the shaft, which is housed, in an extended housing on ratios above 1.5:1 on the range N. When using a 1:1 ratio gearbox it does not matter which shaft is used as the input as the speed will remain constant. However it is important to ensure that the correct shaft is used on higher ratios other wise the unit will end up increasing the speed.

5.2.2 Can I use the bevel gearboxes as speed increasers

All units can be used as speed increasers, by inputting on the output side of the gearbox, however it is important to check that the unit can handle the power and speed. When using as an increaser it is usually the input speed that is important, do not exceed the catalogue recommended maximum speed. Special units are available where the pinion can be put on the through shaft so that two outputs increase the speed, please request details on this.

5.2.3 When I look at the bevel gearbox shaft arrangement/rotational diagrams, how should I interpret these

When looking at the bevel gearbox shaft arrangement diagrams, the gearboxes are shown in plan view, but the actual rotational arrows are representative of the output shaft rotations viewed from the end of the shaft looking directly at it. A good visualisation of the gear arrangement can also be seen on the 3D CAD models for the Range-N bevel gearboxes configurable online. You can view the model with a transparent housing just to check gear orientation.

5.2.4 Is there a safety margin built into the power/torque figures for the bevel gearboxes?

There are safety margins built into the figures, but the tabulated figures should not be exceeded, so that the units work for efficiently and correctly for their intended life time.

5.2.5 What is the best method of fitting couplings to the shafts of a bevel gearbox

It is very tempting to tap couplings onto the shafts using a hide mallet, but this is a method which is not recommend, as a sharp blow to the shaft end can damage the bearings. The preferred method of fitting is to use the tapped hole in the end of the shaft and a bar with a hole drilled through it. Put the correct size screw through the hole and wind the coupling on.

www.powerjacks.com 17 5 Operation

5.2.6 Does my bevel gearbox need a vent

Some of the units in the ranges are supplied with a vent, others are not.

The Range N do not have breathers fitted as standard. All other units are either supplied with breathers pre-fitted, or will be supplied with the unit to be fitted after oil fill. If the unit is to run at very high speeds, then we would suggest fitting a breather, please consult us if you intend to run a unit extremely fast.

5.2.7 Are the bevel gearboxes supplied filled with oil

Range-N is supplied dry (no lubricant). All units will require filling with oil prior to installation. Note - For low speed applications (250 rpm input speed and below) gearboxes may be recommended to have semi-fluid or grease lubrication. Consult Power Jacks for advice.

5.2.8 How often should I change the oil in the bevel gearboxes This depends on how often the unit is run and the type of oil that has been supplied with the unit (if pre-filled). For all other units we recommend changing the oil every six months or 2,500 operating hours.

5.2.9 Is it possible to fill the bevel gearboxes with grease

We recommend filling the units with grease or semi-fluid grease if the units are operating at speeds of 250rpm or below.

5.2.10 What is the maximum recommended case temperature for a bevel gearbox

The case temperature must not exceed 80°C.

5.2.11 Can you manufacturer me a bevel gearbox with special shafts, case material etc?

We can adapt a unit to your specification

5.2.12 Some of the bevel gearboxes have a maximum speed, how is this calculated

The maximum pinion speed is based upon a pitch line velocity of 762M/min (2500ft/min)

5.2.13 How efficient are spiral bevel gearboxes?

The units efficiency ranges from 95 to 98%

5.2.14 I notice that the noise of the unit and case temperature reduce when the units are fully operational.

It is known that the noise and temperature levels do drop when the units are under load, this is due to the bearings and working rather than running idle.

18 www.powerjacks.com Operation 5

5.2.15 Are spares available for the various ranges for bevel gearboxes

The Range-N can be repaired or spares fitted, although it is worth noting that if all internal components need replacing then it would be cheaper to purchase new units. If units need repairing we would recommend returning them to the factory, where they can be rebuilt with the correct backlash and alignment.

When disposing of gearboxes and lubricant please do so in an environmentally responsible manner.

www.powerjacks.com 19 6 Maintenance

6.1 General Maintenance Notes

6.1.1 Maintenance and replacement work must be done by an expert maintenance technicians trained in the observance of applicable laws on health and safety at work and the special ambient problems attendant on the installation.

6.1.2 Before doing any work on the unit, the operator must first switch off power to the bevel gearboxes drive system and ensure that it is out of service, as well as taking all necessary precautions against it being accidentally switched on again or its parts moving without warning.

6.1.3 All additional environmental safety precautions must be taken (e.g. elimination of residual gas or dust, etc.).

6.1.4 Before doing any maintenance work, activate all safety equipment and, if necessary, inform persons working in the vicinity. In particular, mark off the area around the unit(s) and prevent access to any equipment, which, if activated, might be the cause of unexpected health and safety hazards.

6.1.5 Replace worn components with original spare parts only.

6.1.6 Use the lubricants (oil and grease) recommended by the Manufacturer.

6.1.7 When working on the units, always replace gaskets and seals with new original ones.

6.1.8 If a bearing requires replacement, it is good practice to also replace the other bearing supporting the same shaft.

6.1.9 Power Jacks recommend replacing the lubricant after all maintenance work where a unit has been dismantled (completely or partially).

6.1.10 The above instructions are aimed at ensuring efficient and safe operation of the Range-N bevel gearbox

6.1.11 The Manufacturer declines all liability for injury and damage to components due to the use of non-original spare parts and non-routine work, which modifies the safety requirements without the express prior authorisation of the Manufacturer.

6.1.12 Refer to the specific spare parts list when ordering spare parts for products.

6.1.13 Do not dump polluting liquids, worn parts and maintenance waste into the environment. Dispose of all such materials as stipulated by applicable legislation.

20 www.powerjacks.com Maintenance 6

6.2 Regular Maintenance

Also refer to section 6.3

6.2.1 Lubrication of the Bevel Gearbox

6.2.1.1 IMPORTANT NOTE – The bevel gearboxes are shipped dry and are fitted with a warning label. Before operation the gearbox must be filled with the correct lubricant type and quantity.

6.2.1.2 IMPORTANT NOTE – Lubricant suitability is dependent on duty cycle and ambient temperature. However in general recommended lubricants in section 7 are suitable for operation in an ambient temperature of -10ºC to +50ºC. If in doubt consult with Power Jacks prior to installation and operation.

6.2.1.3 The maintenance engineer should establish a lubrication programme based on the bevel gearboxes duty and use.

6.2.1.4 The information given below assumes that the gear unit is positioned with all shafts in a horizontal plane.

6.2.1.5 For input speeds up to 1500 RPM the oil level in the gear unit should be maintained just below the centerline of the shafts. A sight glass or level plug is provided for level indication.

6.2.1.6 A change of oil may be required for speeds of 1500 RPM or above, and Power Jacks should be consulted.

6.2.1.7 For input speeds of 250 RPM or below grease lubrication should be used.

6.2.1.8 Important Power Jacks should be advised when a gear unit is installed with a shaft positioned vertically.

6.2.1.9 If the gearbox uses a grease lubricant then excessive grease application should be avoided.

6.2.1.10 If the bevel gearbox or its system is fitted with a brake ensure that under no circumstances lubricant gets into the brake as this can cause brake failure due to loss of friction.

www.powerjacks.com 21 6 Maintenance

6.3 Lubrication Intervals - General

6.3.1 Regularly check and top up lubrication in the Range-N bevel gearbox(es).

6.3.2 Refer to section 7 for recommended lubricants.

Item Operation Type Lubrication Interval Lubricant Type

Check & lubricate as required Input Speed > 250 rpm = Oil. Refer Section 7 Table 1 1 Normal every 1 month Input Speed =< 250 rpm = Grease. Refer Section 7 Table 3 Check & lubricate as required 2 Arduous Consult Power Jacks for suitable lubricant every 1 week

6.3.3 A new bevel gearbox should be drained after 100 hours of operation and cleaned using a light flushing oil. After this the bevel gearbox oil should be changed every six months or 2500 operating hours.

6.3.4 Where severe operating conditions are encountered more frequent oil changes are advised.

6.3.5 The gear unit should be warm when an oil change is undertaken.

6.3.6 Check oil levels regularly.

6.4 Check Unit Operational Performance

6.4.1 Remove dust / dirt / debris deposits from the unit(s).

6.4.2 Check that noise at constant load does not vary. Excessive vibration or noise can indicate wear of a gear in a gearbox or failure of a bearing.

6.4.3 Check for lubricant leaks from the gaskets/seals, caps and casings.

6.4.4 Check all bolted joints/couplings for wear, deformation or corrosion and tighten them down fully without over tightening.

6.4.5 A periodic check of backlash between bevel gear set is recommended to check wear on internal threads of worm gear. Backlash in excess of 50% thread thickness indicates that a replacement will be necessary to replace the bevel gear set assembly.

6.4.6 If driven by an electric motor check the power absorption and voltage against the nominal values given on the motor’s nameplate.

6.4.7 The bevel gearbox operates with a maximum case temperature of 80°C. If this temperature is exceeded Power Jacks should be consulted.
